dash A/C out on my 2004 Newmar Dutch Star

[IamGadget]

Hello;
Dash A/C went out on my 2004 Newmar Dutch Star. I turn all switches and just dead. I looked for fuse...it looked good so i reversed it and put it back. Any help appreciated. Thank you.

Hi IamGadget,

First consider determining if the entire dash HVAC is not working or just the dash A/C.

When you mention all is dead, I assume there is no fan. If this is correct, it may not be your A/C. There is more than one fuse to check. In the outside basement bay in front of the left front tire there are two fuse panels. My assumption is an 04 DSDP is the same as an 05 KSDP. On the upper fuse/relay panel there is a fuse marked HVAC. On the lower fuse panel check fuse F1 (A/C clutch) and F11 (Fan). Even if the fuses are "good" replace them (this is another story).

Turn the fan speed knob to high. Do you get a fan noise if the HVAC selection knob is turned to any other position (besides the A/C position)? Do you get a fan noise if the fan speed is altered? Does everything else work except the dash A/C? Or, is everything with the dash HVAC dead?

The answers may lead to different conclusions.

Thank you again...thank you. I did not know what a HVAC was (still don't)
That was the bad fuse. I just purchased some spares before i left for my trip. It was a small 25 amp and was blown. Before your note to me all i tried was what sounded like A/C stuff..such as the F1 fuse. I do not know what a 04 DSDP is or the 05 KSDP. I also had a buzzing sound that came on every 3 to 4 seconds for a couple of seconds. It came from under the hood on the passenger side...maybe it is tied into this...i hope.
Thank you so much. I am staying over at flying J in NJ at the moment...i am going inside to see if they have any of these mini fuses...take care...Happy Easter...and enjoy...Allen

I totally agree with the above statement. My two 12 receptacles on the dash would not charge my cell phone or power my GPS. When I tested at the two receptables I measured 12 volts. When I pluged in my GPS it read 0.4 volts. I checked the fuse in the little compartment infront of the front wheel. The fuse looked alittle distorted so I ohmed the fuse, it was open. Changed the fuse and the recepticales were working normal. There must have been enough connection left in the blown fuse to show a voltage but not support a load. From now on I pull the fuse and ohm it after I examine it.

Hi IamGadget,
I'm sorry for using acronyms. It's an Internet thing. We tend to forget how to correspond correctly.

HVAC = Heating Air Conditioning & Ventilation
DSDP = Dutch Star Diesel Pusher
KSDP = Kountry Star Diesel Pusher

I have a KSDP and you have a DSDP. Kountry Star is a step below Dutch Star.

The J should have all the fuses you need. You're lucky to be there.

HiJ
Cig plugs worked..all seemed to work. But the 25amp HVAC fuse went in a few seconds after turning on the das A/C. I did have btwo new roof A/C units just installed...but that is not connected in any way....where do i go from here? Thanks again

Hi Allen,
It is time for the professional service people to get involved. To diagnose a continually blowing fuse, you'll need a meter, lots of time and a lot of patience. When you get to your work location, see if there is a mobile automotive service that can come to you, at the CG. If not, call Newmar and ask for their recommendation. I do not know if this is considered a Newmar or a Spartan problem.
